This type of water trap is designed for negative pressure. Demount
this type of water trap for careful cleaning.
S.5.5 Run-around heat exchanger
A heat recovery system of this type consists of a heating coil in the supply air- flow and a cooling coil in the exhaust
air- flow. After an extended running period (normally a few years) dust particles can accumulate on the surface of the
coils. This can reduce the efficiency of the coils. Cleaning must be carried out with the utmost care to ensure that the
coil fins are not damaged.
The piping system must be vented once a year as air in the system can significantly reduce the capacity of the coils.
S.5.5.1 Pump and pressure expansion
The service instructions issued by the pump manufacturer must be followed. The pressure expansion system must be
checked once a year. If necessary, the pressure must be increased to the correct level.
S.5.5.2 Condensate water drain
Once a year clean the drip tray beneath the heat exchanger, as well as the drain and the water trap. Take care that
there is sufficient water in the water trap. If a droplet eliminator has been fitted to the cooling coil, this must be checked
once a year and cleaned if necessary.
S.5.6 Coils/batteries for heating and/or cooling
After an extended running period (normally a few years) dust particles can accumulate on the surface of the coil. This
can reduce the efficiency of the coil. Cleaning must be carried out with the utmost care to ensure that the coil fins are
not damaged. The piping system must be vented once a year as air in the system can significantly reduce the capacity
of the coil.
S.5.6.1 Heating battery
Check that the frost protection system is fully operational. A battery may
burst due to frost if the frost protection system is not operational.
